A more non-trivial example: Say you want to say that 2 x 4 = 8. One way is to just write 2 x 4 = 8. Another way is to say that a finite set of cardinality 8 is the product of a finite set of cardinality 2 and cardinality 4 in the category of finite sets (in the sense that 8 satisfies the universal property of 2 x 4).
Not sure what you mean by "rot mathematics".
> Meta mathematics, abstract, detached from real life, as alot of the academy with its publish pr perish thinking ... that produces pain.
Some (including me) would say that the meta and abstract mathematics is most beautiful of all...

I think you misread the parent comment (although to be clear, I'm not defending it).
Thanks for taking the initiative to host this.
